Application filed September 22, 1906; Serial No- 835,733.

To all whom, it may concern:

Be it known that I, JOHN STUB, a citizen of the United States, and a resident of the city of New York, borough of Brooklyn, 5 county of Kings, and State of New York,

have invented a new and Im roved Swimming-Machine, of which the ollowing is a full, clear, and exact description.

This invention is an improved swimmingmachine of such construction as to be capable of easy and safe 0 eration and acting when propelled to rapidly drive the swimmer in the water.

One embodiment of the invention consists I of a frame of tubular construction having a pointed forward end between which is fixed a float comprising a hollow body conforming to the frame and which in the preferred form of'invention is shaped like a ci ar. The machine is provided with a keel fixed to the float to revent it from overturning and also provided with suitable repelling means journaled in the rear end 0 the frame.

Reference is to be hadto the accompany- 2 5 ing drawings, forming a part of this specification, in which similar characters of reference indicate corresponding parts in both the figures.

Figure ,1 is a side elevation of my improved 2 is a plan view of the machine.

The invention com rises a frame 1, pref-' erably constructed 0 tubing, the forward portion of which is bent into substantially the shape of a narrow ellipse with a forward pointed end and a rear end extension lying in the same horizontal plane and of contracted Width composedof parallel ortions' 2, connected by a cross-bar 3, therea ter converging into a pointed extremity or bearing 4 at the stern end of the machine. Journaled in the bearing 4 and cross-bar 3 is a short longitudinal shaft 5, having a pro eller 6 fixedto its outer end and a beve gear 7 fixed to its innerend, in mesh with a similar bevel-gear 8, fixed to a crank-shaft 9. The crank-shaft 9, as best shown in Fig. 2, is journaled in the frame transversely of the par- '50 allel-portions 2 and carries at each extremity operator on the surface of the water.

machine, showing the position assumed by a swimmer thereon indotted outline; and Fig.

a crank 10, on which pedals 11 are revolubly mounted.

Fixed to the frame in the elliptical portion thereof and exactl conforming thereto is a hollow body 12, orming a non-collapsible float to buoyantly support the machine lalrliid float, as shown, is cigar-shaped to reduce the resistance of the water to a minimum and carries at its bottom side a heavy keel 13, 6o acting to prevent the machine from overturning.

In the operation of the machine the swimmer outstretches himself upon and facing the float, with his feet..on the pedals, as disclosed in dotted outline in Fig. 1. By now\ working the pedals the machine may be caused to move ineither direction, accordin to the rotation of the ropeller, and the ban of the swimmer may e used in guiding the machine in its movement;

The precise embodiment ofthe invention is not material provided its essentiahcharacteristics are employed as pointed out in the annexed claims. 7 5

Having thus. described my invention, I claim as new and desire to secure by Letters Patcnt 1. In a swimming-machine, a frame cons'tructed of tubing with the forward portion thereof bent into the form of a narrow ellipse,

I a float fixed within the frame between the elliptical portion adapted to buoyantly support the swimmer in an outstretched position, and pro elling means journaled near the rear end 0" the frame and operable by the feet of the swimmer.

2. In a swimming-machine, a frame composed of tubin bent into the form of a narrow ellipse with a rear end extension, a float contained within and fixed to the elliptical portion of the frame, adapted to buoyantly support the swimmer thereon in an outstretched position, and propelling means operable by the feet of the swimmer journaled in said extension. 2

3. In a swimming-machine, a frame com posed of tubinlg1 shaped to the form of anarrow ellipse wit a rear end extension lying in the same horizontal plane, a cigar-shaped I00 float contained within. and fixed to the ellipnaixi'-to fihis'specifioamon 1n me presence of tical portion of the frame'adapted to buoy- 'two subscribing witnesses. antIy su port the swimmer thereon in an I outstretc ed position, and propelling means s p 5 operable by the-feet of the swimmer jou'r-fl .Withessesi v naledin said extension.
